The Station

WWVB, the radio station which broadcasts 60 kHz time and frequency signals, is located in Fort Collins, Colorado, about 100 kilometers north of Denver. It is the companion to the shortwave station WWV.

Transmitter

The 60 kHz transmitter amplifies the time signal before it is sent to the antenna. A 50 Ohm transmission line connects the 60 kHz transmitter in the broadcast house with the antenna. The transmission line begins on huge spools, and is buried in a shallow trench.
